Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed May 556, 1909. Serial No. 198527.

To all whom it may concern:

Be it known that we, \VILLIAM J. Bna'r- 'rin, Enxns'r \V. Boyx'ron, and Eown: B. Crmncnnm, citizens of the United States all residing at l itchburg. in the county of \Vorcester and State of Massachusetts,have invented a new and useful 'llrack-Sander, of which the following is a specification.

This invention relates to a sanding device adapted to be used on street and other cars, locomotives, and the like.

The principal objects of the invention are to provide means whereby sand can be dis tributed by the agency of compressed air in an effective and constant manner and especially to provide 'means whereby the operator of the car can control the supply of sand in a simple and convenient manner so that it will be absolutely. certain that'thc sand will be discharged when it is wanted.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompany ing drawings in which- Figure 1 1s a longitudinal central sectional view of a portion of an electric street 1 carshowing one way in which this invention maybe applied thereto; Fig. 2 is a plan on enlarged scale of the controlling valve box for the sand distributer; Fig. 3 is a central sectional view of the same; Fig. t is a bottom perspective view of the valve proper, and Fig. 5 IS a central vertical section 0t certa n features of the sand distributing de vice itself.

provided ".vithan outlet port 18 co1n'muni-- eating with the other branch 19 of. the compressed air pipe.

On the casing 17 is mounted a .cap 20 adapted to be removably secured in place and in the casing is acircular recess 21 into.

the bottom of which the orts 16 and18 enter preferably at points iametrically up posed. Within this recess is a circular valve 22 having a diametrical gr'oove or passage 23 inits bottom surface so that when turned to a certain position it will open communication between the-ports16 and 18 but will close both of them in all other positions. A spring 24 is shown in the recess bearing on the valve and on the cap 20 to hold the valveto its seat.

The valve is provided with a stem 25 which extends up through the .cap and has a square port on 26 thereon on which fits a handle 27. This handleis pro \ided with a pointer 28 to indicate by means of the words On and Off or the like on the top of the cap the condition of the comnmn 36'which is secured to the bottom ofithe sand hopper 37.

This column has 'an unobstructed vertical passage 38 therethrough communicating with the interior of the hopper and with a horizontal passage 35) at the bottom of it. The pipe 19 enters this passage 39 and it preferably is provided with a nozzle 40 having a discharge opening 41 in the end located under the center of the passage 38. This nozzle is spaced from the walls of the passage 39 and train its position it is obvious that the sand will be discharged by the compressed air in a continuous stream into a discharge pipe 12 which extends from the opposite end of the passage 39. This pipe is bent upwardly at its end 49 to prevent accidentaLleakage of sand'and is.

connected with a hose 13 for discharging the sand on the track, this hose being held in any desired position at a point near the wheel. The bottom of the passage 39 is pro vided with a clean-out passage 44 adapted to be closed by a removable plug 45.

It will be understood, of course, that each car can be pi'oviileclavitli two or more of these devices as desired, and that they can be located in many other positions than that shown. \Ve are aware also thatthe invention can be adapted for use on vman -.other kinds of cars, locomotives, and the li is than that illustrated-in the drawings, and that .sand connected atone end of the passage, a

compressed air pipe connected with the other end and having a nozzle extending part wayalong the passage for discharging the air and sand into the pipe, a compressed air reservoir connected with said pipe, and a valve in said pipe comprising a rotatable -disk having a slot across one face thereof adapted to communicate with the pipe.

2. In a device for cars and the like, the combination of a compressed air reservoir, a vertical passage for feeding sand, a pipe connected with the reservoir and having a nozzleprojecting under said vertical pas sage, and a valve for controlling the passage of air to said nozzle, said valve comprising a casing having two ports, one connected with the reservoir and the other with the nozzle, a valve proper in said casing provided with a slot across the face thereof adapted to communicate with both of said ports in one position thereof and with neither of them in all other positions, and a handle on the outside of the casing for turning the disk.

3. In a device of the character described, the combination of a. casing havin inlet and outlet ports for compressed air and-provided with a circular recess therein into the bottom of which said ports open, said ports being diametrically opposed to each other with respect to said recess, and a circular valve disk rotatably mounted in said recess and having a diametrical passage thereacross for connecting said ports.

4. In a device of the character described, the combination of a casing having inlet and outlet ports for compressed air and provided with a circular recess therein into the bottom of which said ports open, and a circular valve rotatably mounted in said recess and having a passage thereacross for connecting .said ports, a cap removably mounted on the top of the casing, a spring under the cap for holding the valve down on its seat, a valve-stem extending up-through the cap, and a handle on the valve stem for turnin the valve. I

In testimony whereof we have hereunto set our hands, in the presence of two subscribing witnesses.
